DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS
[0012] The making and using of the presently preferred embodiments are discussed in detail below. It should be appreciated, however, that the present disclosure provides many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed are merely illustrative and do not limit the scope of the disclosure.
[0013] The present disclosure will be described with respect to preferred embodiments in a specific context, namely a wireless fidelity (Wi-Fi) wireless standard, which may also be known as IEEE 802.11. The concepts in the disclosure may also apply, however, to other types of communications standards for connecting electronic devices or access networks.
[0014] In the current WFA hotspot 2.0 release 2 standard, a user selects the OSU based on the information of the OSU NAI 16 as shown in Figure 2, but this information generally is not enough. For example, a user may want to consider what type of additional services the OSU offers. Another example is that a user may want to access a basic service set (BSS) that is deployed by the OSU provider, which may provide the lowest price for service.
[0015] As used herein, the OSU provider may be a Wi-Fi provider or a Wi-Fi hotspot operator or may be another entity altogether. For example, the OSU service provider may provide network access service itself or operate a Wi-Fi hotspot. In contrast, if the OSU service provider has no Wi-Fi network the OSU service provider may borrow or rent a Wi-Fi network from a hotspot operator.
[0016] As will be more fully explained below, an embodiment method assists with selection of online sign up provider by providing some information via ANQP message or some other message. In an embodiment, the relationship between OSU provider and the BSS is set and sent to the user device from the network to user devices for helping select OSU provider to process online sign up. Embodiments may be implemented in Wi-Fi networks and user devices, such as a Wi-Fi access point (AP), a Wi-Fi station (STA), and the like.
[0017] An embodiment method provides additional information on OSU characteristics or OSU provider's characteristics or preference in some pre-association message (e.g., ANQP message or beacon), so that this information can be used by the user or user device to select the OSU provider to get a subscription. This information may be referred to as OSU selection information. As used herein, the OSU selection information excludes the following information pertaining to the OSU provider: their friendly name (in multiple human languages) 14, the network access identifier (NAI) 16 to be used to authenticate to the Wi-Fi access network (when configured for WPA2-Enterprise security), the universal resource identifier (URI) of their OSU Server 18, and their Icon(s) 20. In an embodiment, an OSU selection information field 22 is added to the ANQP message 24 as shown in Figure 3. As shown in Figure 4, the OSU selection information field 22 may indicate a relationship between OSU provider and BSS.
[0018] In an embodiment, the OSU selection information representing a type of relationship of OSU provider and BSS is sent via ANQP message 24 or some other element or message (e.g., beacon), more specially, via the "Hotspot Online Sign-Up (OSU) Providers list" (in Figure 1) and "OSU Provider field" (in Figure 2) element. The relationship may indicate whether this BSS (the one that is sending the ANQP element to the user device) is the OSU provider's most preferred BSS, or a priority value of this BSS for the OSU provider, and so on. An example is shown in Figure 4 of relationship information being included in the OSU selection information field 22 of Figure 3. Another example is provided in the table 26 of Figure 5 (most preferred BSS), the table 28 of Figure 6 (own deployed BSS option), and the table 30 of Figure 7 (priority order option). The relationship defined in these tables are merely examples and do not limit other possible definitions of the relationship.
[0019] The OSU provider may set the relationship value based on its relationship with the BSS. For example, if this BSS is its own deployed BSS, it will set the highest priority for this BSS, or if this BSS operator gives the OSU provider a good price for a roaming agreement, it will set the second highest priority for this BSS, and so on. These are just some examples for how to set the relationship, but do not limit embodiments for other implementations of the relationship.
[0020] When the user device receives this information, the user device can show this information to the user for the user to select a suitable OSU provider, or the user device can select directly based on the configuration policy (e.g., the user sent the configuration policy to the user device to select the OSU provider of the highest priority BSS who has the best signaling strength).
[0021] In an embodiment, the BSS (operator) sets the relationship value based on its relationship with the OSU provider. For example, if this OSU provider is its operator, it will set the highest priority for this OSU provider, or if this OSU provider gives the BSS (operator) a good price for a roaming agreement, it will set the second highest priority for this OSU provider, and so on. Again, these are just some examples for how to set the relationship, but do not limit other embodiments with other relationships.
[0022] The relationship of OSU provider and BSS is sent via ANQP element or some other message (e.g., beacon), more specifically, via "Hotspot Online Sign-Up (OSU) Providers list" (in Figure 1) and "OSU Provider field" (in Figure 2) element. The relationship may indicate whether this BSS (the one that is sending the ANQP element to the user device) is the OSU provider most preferred BSS, or a priority value of this BSS for the OSU provider, and so on. An example is shown in Figure 4 of relationship information being included in the OSU selection information field 22 of Figure 3. Another example is provided in the table 32 of Figure 8 (most preferred OSU provider), the table 34 of Figure 9 (own deployed BSS), and the table 36 of Figure 10 (priority order). A further example is shown in Figure 1, where the OSU providers listed in the OSU provider list 12 element are listed by the order of their priority (e.g., OSU Provider #1, OSU Provider #2, ... OSU Provider #N). When the user device receives this information, the user device can show the information to the user for the user to select a suitable OSU provider, or the user device can select directly based on the configuration policy.
[0023] In an embodiment, a Wi-Fi network component (could be an ANQP server, an AP, or AP controller or some other Wi-Fi component) provides additional information about each OSU, which information can be used by the user for OSU selection. Examples of such information are cost of subscription, access to various services, minimum quality of service (QoS) guaranteed, etc. The additional information is sent via ANQP message 10 or some other element or message (e.g., beacon), more specifically, via "Hotspot Online Sign-Up (OSU) Providers list" (in Figure 1) and "OSU Provider field" (in Figure 2) element in OSU attributes. Figure 11 illustrates example OSU provider field 22 format (e.g., the OSU selection information field). Figure 12 illustrates OSU attributes 38 within the OSU provider field 22. The OSU attributes 38 have the following structure: 1 byte the OSU attribute type 40, 1 byte the OSU attribute value 42.
[0024] In an embodiment, the information for the OSU selection in the OSU selection information field 22 can be a kind of introduction of the OSU provider (or service provider), or an advertisement from the OSU provider. This introduction or advertisement can be a kind of text transferred from the network to the user device (e.g., via ANQP message of Hotspot Online Sign-Up (OSU) Providers list format, or some other messages). For example, it can be as "the best user experience in the world with a lowest and flexible rate," or "it is a network from CMCC providing all over the world coverage and roaming." When the user device receives this information, it can show it to the user and wait for the user's input, or it can handle it by itself. For example, it can pick up key word and check the pre-configured key-word in itself. If the key word matches one of the pre-configured key words, it will handle it according to the pre-configured process link to the pre-configured key word.
[0025] Figure 13 illustrates a OSU attributes type table 44. Figure 14 illustrates an example table 46 with a value field for available services. Another example is that the available services are listed as a bit map and each bit indicates a service. When a bit is set to 1, it means that the OSU provider provides the corresponding service. When the user device receives the ANQP message it will display a list of OSU names, and optionally will display the OSU attributes to allow the user to make an information selection.
[0026] Figure 15 illustrates a wireless cellular communications network 48 that preferably comprises a plurality of base stations (BS) 50 providing voice and/or data wireless communication service to a plurality of mobile stations (MS) 52. The BSs 50, which may also be referred to by other names such as access network (AN), cellular access point (AP), a cellular network communications controller, Node-B, etc., preferably downlink (DL) information to the MSs 52 while also receiving uplink (UL) information from the MSs 52. In an embodiment, the MS is smart phone has both Wi-Fi and cellular network communication connectivity.
[0027] Each BS 50 preferably has a corresponding coverage area 54. These coverage areas 54 represent the range of each BS 50 to adequately transmit data, and, while not necessarily shown, the coverage areas of adjacent BSs 50 preferably have some overlap in order to accommodate handoffs between BSs 50 whenever a MS 52 exits one coverage area 54 and enters an adjacent coverage area 54. Each BS 50 also preferably includes a scheduler 56 for allocating radio resources to the MSs 52.
